Accelerated version wan diagram generates diagram v1

This is a WAN that accelerates card drawing with CausVid, capable of high-speed card drawing at a 960X540 resolution, and it has a great understanding of prompts! Each draw takes a little over 3 minutes on average and costs less than 1 yuan. Don't underestimate the quality of WAN's visuals; the 960 resolution performs quite well under many scenarios. We will release a higher resolution version after finding better video memory optimization solutions. For this version, remember not to exceed a 960X540 resolution, as it will cause video memory overflow.
